Apart from the main drills, Iran’s Navy commando units are conducting special operations in the southeastern Makran region.

Last June, Sayyari said that Tehran was planning to carry out 20 military drills before March 2017.

Iranian officials insist that the war games do not violate the Joint Comprehensive Plan of Action (JCPOA) – the nuclear deal between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) signed in January of 2016.

The UN nuclear watchdog said on Saturday that Iran has been found to be in full compliance with the nuclear deal, but the report comes against a backdrop of rising tensions between Tehran and Washington.

Earlier this month, then-US National Security Advisor Michael Flynn said that “Iran had been put formally on notice” after Tehran fired a ballistic missile.

Later in February, President Trump tweeted that “Iran is playing with fire,” promising that he won’t be as “kind as [former President] Obama.”
